Montezuma oropendola Psarocolius montezuma

Spectacular, very large ‘blackbird’ of tropical lowlands. Favors forest edge, open woodland, plantations, semi-open areas with trees; colonies of large pendulous nests adorn tall trees. Male is much larger than female, but sexes look similar: dark rusty overall with a black head, bold yellow sides to the tail, and ornate face and bill patterning. Flies rather directly, with slow, ‘rowing’ wingbeats. Memorable gurgling song sounds like water poured from a bottle.
